The present invention relates to a positioning device, and a structure of a positioning device such as a stand for standing up a flat electronic device such as a tablet computer or a tablet terminal or an electronic device such as a general-purpose display of a liquid crystal display (LED) or an organic EL (OLED). Regarding

In a flat electronic device that can be installed on a table, there is a demand for a support structure, a so-called positioning device, that can change the installation angle, that is, the posture, in a plurality of steps.

For example, Patent Document 1 discloses an arm stand as shown in FIG. 1 as a conventional positioning device. The arm stand is an arm 4 that supports a flat holder 2 that holds the flat display 1, and a first rotation that is at one end of the arm 4 and that rotatably connects the arm 4 above the holder 2.

JP, 2011-43858, A

However, the positioning device having the above structure has the following problems (1) to (3).
(1) Since the base 6 supporting the holder 2 and the arm 4 supports its own weight including the display 1, it is necessary to fix it to the end of the table 102 to be mounted by sandwiching the top plate or the like with a tightening screw (clamp structure). Therefore, in the case of a table or the like which does not have a top plate edge portion that can be sandwiched, that is, an eave structure having a sufficient length to be sandwiched, the positioning device cannot be fixed and stand alone.
(2) The display 1 may not be placed near the center of a relatively wide table due to the fixed position of the clamp structure at the table edge and the length of the arm 4.
(3) Since the first and second rotating portions 3 and 5 are the rotation holding mechanism that uses friction and spring force assisted friction, the tilt angle can be maintained only by the display 1 having a certain weight.

Therefore, the present invention has been made in view of the above-mentioned points, and an electronic device can be arbitrarily placed at any position on a table or the like regardless of the weight of the electronic device without using spring force assisted friction or the like. It is an object of the present invention to provide a positioning device that can be installed upright at an angle.

The positioning device of the present invention is a positioning device for fixing an electronic device having a housing having a display surface on the front surface while determining an angular position with respect to a board surface,
A holder for holding the back surface of the housing of the electronic device,
A base portion carried on the board surface,
A projecting support portion having a first connecting portion rotatably connected to the base portion at one end thereof and a second connecting portion rotatably connected to the holding portion at the other end opposite to the one end;
A stopper portion that is extendable from the base portion and locks one end of the housing of the electronic device,
It is characterized by including.

According to the present invention, there is an effect that the electronic device can be erected at an arbitrary position on the table or the like at an arbitrary angle regardless of the weight of the electronic device without utilizing the spring force assisted friction or the like. ..

(First embodiment)
(Description of configuration)
FIG. 2 is a perspective view showing the positioning device 10 of this embodiment, and FIG. 3 is a side view showing how the display device 301 having a housing having a substantially flat outer shape is mounted on the positioning device 10 of this embodiment. The display 301 has a display surface (not shown) on its front surface. 3A shows a state before the display 301 is mounted on the positioning device 10 on the top plate of the table 302 such as a desk, and FIG. 3B shows a state after the display 301 is mounted on the positioning device 10. The situation is shown respectively.

The positioning device 10 includes a holding portion 35 that holds the back surface (rear surface) of the display 301, a base 31 that is arranged under the housing of the display 301, and a first connecting portion that is rotatably connected to the base 31 at one end. And a protrusion 33 having a first hinge 32 and a second hinge 34 that is a second connecting portion rotatably connected to the holding portion 35 at the other end opposite to the one end, and is extendable from the base 31 and And a stopper portion 36 that locks the lower end of the casing of the display 301.

As shown in FIG. 2, the base 31 installed on the top plate (board surface) of the table 302 such as a desk is a tray-shaped plate-like body having peripheral walls on the left and right sides and the rear side and forming a quadrangle in a plan view. There is a base bearing portion 31b fixed by a screw at the center position of the upper surface. Within the area of the base 31, that is, within the peripheral wall, the first hinge 32, the protruding portion 33, the second hinge 34, and the holding portion 35 connected on the base bearing portion 31b are housed.

The stopper portion 36 is a plate-like member having a U-shape in a plan view, and the pair of strips extending in parallel along the left and right peripheral walls of the base 31 have long holes 36a parallel to each other. A hook 36b that supports the entire display 301 by connecting a pair of strips and hooking the lower end of the display 301 is provided on the front side of the stopper portion 36. The stopper portion 36 is configured so as to be slidably fixed to the base 31 by a pair of knob fixing screws 37 provided upright on the base 31 through both elongated holes 36a. The stopper 36 can be fixed by the elongated hole 36a and the knob fixing screw 37 so that the hook 36b can be extended and retracted back and forth on the display 301 while the hook 36b projects substantially parallel to the base 31.

Both wings of the first hinge 32 are screwed to the rear end portion of the base bearing portion 31b of the base 31 and the rear end portion of the projecting support portion 33, respectively, and the projecting support portion 33 is rotated back and forth with respect to the base bearing portion 31b. Dynamically connect.

Both wings of the second hinge 34 are respectively screwed to the front end portion of the protruding portion 33 and the rear end portion of the holding portion 35, and the holding portion 35 is pivotally connected to the protruding and supporting portion 33 in the front-rear direction.

The holding portion 35 is a basin-shaped plate-like body which has a rectangular shape in a plan view and has peripheral walls on the left and right sides and the front and rear sides, and has left and right peripheral walls having flanges protruding left and right, and the flanges have a display 301. Has a mounting hole 35a for fixing the.

In this way, the protruding portion 33 and the holding portion 35 have a structure in which the base 31 has two rotatable movable portions including the first hinge 32 and the second hinge 34. The first hinge 32 and the second hinge 34, which are the two pivotally movable parts, are not necessarily torque hinges, but hinges that do not utilize friction and spring force assisted friction like those of a conventional stand with a torque hinge. But it's okay.

(Explanation of operation)
As shown in FIG. 3A, the display 301 is positioned from above the holding portion 35, and the mounting hole 35a of the holding portion 35 of the positioning device 10 is aligned with the female screw hole (not shown) on the back surface of the display 301. As shown in FIG. 3B, the display 301 is fixed to the holding portion 35 with the fixing screw 301a.

If the holding portion 35 is fixed near the lower end of the display 301, excessive torque may be applied to the second hinge 34 due to its own weight. Therefore, the holding portion 35 should hold more than the middle portion of the rear surface of the housing of the display 301. It is preferably attached. It is also preferable that the holding portion 35 is arranged at a position closer to the upper end of the housing of the display 301 than the lower end of the housing of the display 301.

As shown in FIG. 4A, with the display 301 fixed to the holding portion 35, the lower end of the display 301 is hooked on the hook 36 b of the stopper portion 36. When the knob fixing screw 37 attached to the base 31 is loosened, the stopper portion 36 slides back and forth (extends and contracts) within the range of the long hole 36a as shown by the white arrow in FIGS. 4(a) and 4(b). It can be fixed at any position by tightening the knob fixing screw 37.

When the stopper portion 36 is contracted, the lower end of the display 301, which is hooked on the hook 36b, moves to the rear side, but the first hinge 32 that does not move and the protrusion 33 that moves around the first hinge 32 cause the display 301 to rise ( On the contrary, when the stopper portion 36 is extended, the lower end of the display 301 moves to the front and the display 301 can be laid down (FIG. 4(a)).

Further, by supporting the lower end of the display 301 with the stopper portion 36, the first hinge 32 and the second hinge 34 can maintain the tilt angle without using friction and spring force assisted friction. Therefore, the tilt angle does not depend on the weight of the display 301.

(Explanation of effects)
Since the stopper portion 36 integrated with the base 31 is provided, the positioning device can stand on the table.

Since the stopper portion 36 fixed to the base 31 by the knob fixing screw 37 and slid forward and backward, the positioning device does not fall over because the display 301 is always positioned on the base 31 regardless of the tilt angle. ..

Since the display 301 is always positioned on the base 31 regardless of the angle, the display 301 is stable and the whole body does not fall down. Therefore, like the conventional stand, the base 31 is fastened to the end of the table 302. Since it is not necessary to fix the table top plate by sandwiching it with screws, the display 301 can be placed near the center of the table or the like.

In the first embodiment, an example in which the positioning device is applied to the independent display 301 has been described, but another example of use is an electronic device mounted on the positioning device in front of the operator as shown in FIG. It is also possible to dispose the input operation touch panel 51 (or a flat electronic device such as a tablet computer or a tablet terminal) and to dispose a general-purpose display 52 with a stand on the rear side thereof. Further, if a positioning device is used, multitasking operation is possible without disturbing the screen display of the rear display 52.

In the second embodiment, in addition to the positioning device of the first embodiment, as shown in FIG. 6, the base 31 includes a fixing hole 31a having a fixing structure for fixing the base 31 itself to a structure therebelow. Other than that, it is the same as the first embodiment.

As described above, according to this embodiment, the fixing holes 31a extending in parallel along the left and right peripheral walls of the base 31 are provided, and the table 302 is fixed by screws (not shown) through the fixing holes 31a in the base 31. If it is fixed to, the electronic device and the positioning device will be more stable.

In the third embodiment, as shown in FIG. 7, the protrusions 33 of the positioning device of the first embodiment can be expanded and contracted so that the first protrusions 33a and the second protrusions 33b can be contact-joined. The structure is the same as that of the first embodiment except that the structure is flexible.

As shown in FIGS. 7 and 8, the projecting support portion 33 has a first projecting support portion 33a to which the first hinge 32 is fixed and a second projecting support portion 33b to which the second hinge 34 is fixed. 33a and the 2nd protrusion part 33b are provided with inclined surfaces 33aa and 33bb which make surface contact in the direction which intersects with the direction of expansion and contraction, respectively.

The first protruding portion 33a has a long hole 33ac inserted in the front-rear direction, and is screwed to the second protruding portion 33b by a pair of knob fixing screws 33d. A knob fixing screw 33d is inserted from a direction orthogonal to the elongated hole 33ac, and a knob of the fixing screw is turned to sandwich and press the second protruding support portion 33b through the elongated hole 33ac so that resistance is given and fixed and locked. It is configured. In addition, when it is desired to stop the flat electronic device at an arbitrary angle position due to tilting, turn the knob fixing screw 33d to loosen it and slide the inclined surfaces 33aa and 33bb against each other, and tighten the knob fixing screw at the arbitrary angle position. If locked, the flat electronic device can be supported at that angular position. In this way, it is possible to realize a retractable structure in which the second hinge 34 at the upper end of the protrusion 33 is retractable from the base 31.

As described above, according to the present embodiment, the holding portion 35 can be fixed at a predetermined position on the rear surface of a flat electronic device such as a general-purpose display having various shapes and weights, and the electronic device and the positioning device can be further improved. Stabilize.

In the fourth embodiment, in addition to the positioning device of the first embodiment, as shown in FIG. 9, a holding portion 35 is provided with an iron plate 35F having a magnetic attraction structure for magnetically attracting a housing of a flat electronic device. Other than that, it is the same as the first embodiment.

By providing the iron plate 35F integrated with the holding portion 35 shown in FIG. 9, when a magnet (not shown) is provided at a predetermined back surface corresponding position of the flat electronic device casing, the electronic device is stabilized by magnetic attraction. Can be held. The same effect can be obtained when a magnet sheet (not shown) is attached to a predetermined back surface corresponding position of the housing of the electronic device.

As described above, the electronic device and the positioning device are further stabilized by this embodiment.

The configurations of the above-described first to fourth embodiments can be arbitrarily combined to realize a positioning device with a tilt function that can freely change the angle of a flat electronic device. According to the first to fourth embodiments, even if installed in an arbitrary position such as a table, tilting is possible, and even flat electronic devices such as general-purpose displays having different shapes and weights do not lose their functions. ..
